yes 2.5 ghz core 2 duo t9300
penryn

ya got to figure out a way to lower the lowest voltage
my "idle" temp with a browser and msn on is around 45 degrees, want to lower it if possible

same here... my laptop used to be a lap fryer, and i live in florida i don't need one...
but even at .9500 its still about 45ish +/- 3 at idle... i wanted something in the mid to low 30s idle and 40-50's max... i mean these are 45nm penryn's for pete's sake...
they shouldn't be hotter than meroms...

what kinda video card do you have? i have a 9500m gs which could be the issue. idle temp is around 45 degrees

whatever the hp 14" comes with the 8400m gs?? which i think is a 9300m gs?? same thing?

i found this in a different thread:
1) set the FID/VID transition time to 50us (or a bit higher) - this allows time for the processor to stablize before changing VID
2) set the p-state transition method to "perform single step transition only" - this makes sure that the transition between different FID/VID's will not change so significantly that it destablizes your computer

i applied the settings haven't uv'ed again...

i get this:
Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.
FATAL ERROR: Rounding was 0.4921875, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 0 minutes 58 seconds - 1 errors, 0 warnings.
Execution halted.

does that mean i can't go lower??


this was in orthos...

HWMonitor said my ACPI sensor hit over 6000 F, so the program (Or the sensor itself) clearly glitches at times.

I'm idling at 45 even with a 9500 GS

Not exactly, the 9xxx series cards are the same basic core, but they are smaller and produce less heat

Heres the result after 30 minutes:

I sort of forgot the first time's results as the hwmonitor was being odd.. hopefully this is decently cool?

Now that looks much better and normal. When you have free time, do another test of your highest multiplier for like an hour or more. But I think it should be fine now.

oops i meant to type 45 degrees on idle
